膜分离技术在大型养殖场沼液处理中的应用与展望

大型养殖场沼液具有产生量大且集中、养分含量低、可能含有抗生素残留等特点，若处理不当易对环境造成污染。膜分离技术可对污染物进行高效分离去除且操作简单，因此受到了广泛关注。本文总结分析了应用于大型养殖场沼液的膜分离技术工艺，通过比较分析不同膜分离工艺对养殖场沼液中碳、氮、磷和抗生素等污染物的去除效果，对膜分离技术在养殖场粪污处理方面的未来发展趋势和重点进行了展望，为膜分离技术在养殖粪污处理利用领域的广范应用提供科技支撑。

Research progress on membrane technology for treatment of husbandry biogas slurry and wastewater

The biogas slurry produced by large-scale farms is bulky and concentrated, with low nutrient content and may contain antibiotic residues. Improper handing can easily result in environmental pollution. Membrane separation technology can separate and remove pollutants efficiently and is easy to operate; therefore, the process has attracted wide attention. This paper summarizes and analyzes the membrane separation technology applied to biogas slurry of large-scale livestock farms. By comparing and analyzing the removal effects of different membrane separation processes on pollutants such as carbon, nitrogen, phosphorus, and antibiotics in biogas slurry of large farms, the future development trend and key points of membrane separation technology in manure treatment of livestock farms are explored, providing scientific and technological support for the wide application of membrane separation technology in the field of manure treatment and utilization.
